Episode notes
Cologuard Negative Then Fiber Backfire
- David pursued colon screening after learning about a study linking runners to higher rates of advanced adenomas and chose Cologuard before a colonoscopy.
- He received a negative Cologuard result and then increased dietary fiber, which caused severe gastric discomfort.
Steady Running Bridges Easy And Hard Days
- Steady running lives near the top end of zone two around LT1 and fills the 'medium' training slot between easy and hard workouts.
- David recommends long steady runs and 10–20 minute steady segments after workouts to improve lactate shuttling and Z2 efficiency.
Use Passive Heat Weekly For Blood Volume Gains
- Use passive heat (sauna/hot tub) regularly to expand plasma volume and lower resting heart rate as a low-effort performance stimulus.
- Even one sauna or hot tub session per week on a rest day can accumulate benefits; longer protocols show larger effects.
